This tree standing alone next to the greenhouse in Monet’s garden at Giverny is a holly.
Not a wild, ordinary one: it has beautiful golden rimmed leaves. Nonetheless, the holly disappears in the magnificence of flowers during the season, when the garden is in full bloom. Nobody takes any notice of the flowerless tree.
During the winter, on the contrary, when all the flowers are dead or waiting for better times to come, the holly recovers its majesty. This is probably why its prickly leaves and red berries are very much related to the time of Christmas and New Year.
